Description

The Cold-Drawn Stainless Steel Seamless Tube is manufactured through a precision cold-drawing process that enhances dimensional accuracy, surface finish, and mechanical properties. This method involves pulling a hollow billet through a die at room temperature, resulting in a uniform wall thickness, tight tolerances, and a smooth, weld-free surface. The cold-working process also increases tensile and yield strength compared to hot-rolled tubes. Ideal for high-pressure, high-precision, and critical environment applications.

Mechanical Properties

Note: Cold-drawn tubes typically exhibit higher strength than annealed tubes due to work hardening.
